Via Separations Raises $36 Million to Deploy Commercial Projects, Expand into Refining and Chemicals Markets

WATERTOWN, Mass. — 01 April 2026 — Via Separations, a leader in process solutions for industrial separations, today announced $36 million in new funding with significant participation from new investors including Climate Investment, Aramco Ventures, and Marathon Petroleum Corporation alongside participation from existing backers including Embark Ventures, The Grantham Foundation for the Protection of the Environment, Massachusetts Clean Energy Center (MassCEC), and Safar Partners.

The investment will accelerate deployment of Via’s modular filtration platform into the refining and chemical sectors, building on proven commercial performance in pulp & paper and helping industrial operators reduce energy use, improve uptime, and strengthen operational resilience.

Via electrifies heat-based separation with modular filtration systems that integrate directly with existing equipment, drastically reducing the energy required for chemical separations. These thermal separation steps account for roughly 12% of global energy use, driving significant fuel and steam demand across industrial separations. By replacing them with a mechanically driven membrane process. Via’s system can reduce energy use at the separation step by up to ~90%, delivering lower operating costs, higher uptime, and a more flexible pathway to electrification.

The company has proven the technology at commercial scale in the pulp & paper sector with more than 20 months of continuous operation at a pulp mill in Grande Prairie, Alberta. Via is now expanding deployment into refining and chemicals, with hundreds of millions of dollars of capital projects in the commercial pipeline. The company also completed a pilot at a major Gulf Coast refinery last year.

“Thermal separations represent one of the largest and least-addressed sources of industrial energy consumption,” said Mike Bishop, Investment Director at Climate Investment. “Via’s innovative membrane platform introduces electrification to processes that have depended on heat for more than a century. By seamlessly integrating into existing industrial infrastructure, the company provides a practical solution for reducing energy consumption, enhancing reliability, and significantly lowering emissions.”

“At Aramco Ventures, we invest in differentiated technologies that can deliver clear operational value at scale,” said Tibor Toth, Senior Investment Director at Aramco Ventures. “Via Separations’ modular platform addresses a critical step in industrial processing and has strong potential to enhance efficiency and unlock additional capacity within existing refining and chemical assets.”

“By proving our technology commercially in one sector, we’ve built the foundation to scale into the much larger refining and chemicals markets,” said Shreya Dave, CEO of Via Separations. “This investment enables us to deliver more commercial projects across the product portfolio, expand manufacturing capacity, and accelerate global adoption of membrane‑based separations.”
